I hate that Safari will automatically present PDFs for viewing; every time you browse back to the page, you have wait for the document to be downloaded again; it does not persist if you disconnect from the network; etc.

While I had used the Terminal command defaults write com.apple.Safari WebKitOmitPDFSupport -bool YES with success for a long while, it apparently was broken by the recent release of Acrobat 7.0.7.

However, by navigating to /Library/Internet Plug Ins, I simply moved the (updated) AcrobatPDFViewerPlugin to the "Disabled Plug-ins" folder. Relaunched safari, and relaunched Acrobat, and it seems like the choice is respected -- now PDFs download like they should.

And after removing the offending plugin for Safari, I always venture into Applications>Microsoft Office>Office>Startup and remove the Acrobat files from each of the Excel, Powerpoint, and Word folders.

That Acrobat toolbar in MS Office doesn't seem to have a purpose other than to annoy me.

Once again, this is the definitive trick to get rid of Acrobat stuff in Office: in the 'Microsoft Office'/Office/Startup folder, there are 3 folders: Excel, PowerPoint, Word. In each of them you have to create a *folder* with the name of the annoying Acrobat additions. More precisely:
- in the Excel folder, create the folder "PDFMaker.xla"
- in the PowerPoint folder, create the folder "PDFMaker.ppa"
- in the Excel folder, create the folder "PDFMaker.dot"

Actually, unchecking the preference doesn't "stick", which is, I think, the point of the article. The next time you open a PDF with acrobat or reader, the preferences reset themselves so that the next time you view a pdf in Safari, the adobe plugin launches. I've had this happen numerous times.

much better solution. responds to cmd period and actually stops and PDF loads much faster than that dreaded acrobat inyourface. used it for a year, seemless integration with safari and has never crashed

First, I'm annoyed that both Safari and Acrobat ignore the user and try to offer features I simply do not want enabled.

Second, I'm even more annoyed that (blame either Acrobat or Safari here) the previous hint STOPPED working all of a sudden. Thanks for the heads-up that my former preference would be ignored.

Finally...I'm bummed that this particular hint didn't work for me. I did everything (unchecked pdf support in Quicktime and Acrobat as well as moved the plug-in to the disabled plug-ins folder). Seems I'm now cursed with PDFs buried in Safari (hence my use of Firefox more often these days). The hint to use that other plugin is a good one (just installed it)...thanks!

Personally, I enjoy PDF's opening in my browser. But I do think they opened up to slow.

BUT! i think i found the problem. In the Adobe preferences, there is a setting which allows you to tell it what kind of internet connection you have. Mine was set on 56Kbps... so obviously i changed it to LAN Speed (i'm on a cable modem) and now PDF's open up almost instantaneously.

I hope this is doing what i think i'm doing. I'm going to do more testing. But i would love to hear from others and see if this helps the slow PDF opening of Adobe Acrobat.
